TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALEXANDER Ross, of'Fre'eport, in the county ofStephenson, in the Statev of Illinois, have invented a new and usefulImproved Wagon-Jack; and I do hereby declare that the following is aAfull, and exact description thereof, reference being had totheaccompanying dra`wings,'and to the letters of referencel marked thereon,making a. part of this specicatiomiin 'which- Figure 1 is an elevation.of Iny invention. l

Figure 2, a perspective representation of the lock which su'pports thelever' for raisingtheaxle.

The natuneof my invention consists in the use of a peeuliarshaped lock,arranged lwith a loop, through which a notched standard is made topassi, and anarm between itand the lever which supports theaxle, for the'attachment of a latch which holdsI the 'lever in position under theaxle; and a lug atvthe opposite side ofthe lock from-.the loop for theattachment of the'lever, 'the whole being conveniently arranged forr'aising the axles of all kinds of vehiclesr i I In order to give acorrect understanding of Iuy invention, I have markedvebrrespondiugparts with similar letters,-aud will now give a. detailed description. l

A represents a foot or base-block, which is bolted lfast'to n. notchedstandard, B, and used to prevent 'said standard from settling in theground when, sustaining a greatweight. This standard is `made of wood,and witha. series of notches, J, for the support of a loop, F, throughwhichit 4is made to pass, 'saidv notches being used for adjustingalever, C, to the height of `an axleto be raised. 'E F iswhat I term' alo'ck made of' iron, and with a. loop, F, arranged to slide en standard'B,and rest on either of the notchesJ, and an arm, E, projecting upwardto a suitable point, for supporting a. catch, D, to which it is securedby means of' a bolt, III, as a joint. It also has a lug, G, rigidlyattached to it, for the support of the lever C, whieh'is -bolted fast,that part of ythe lock, shown at I, being long enough to permit saidleverto fit in a seat between 'the'lug G andtlxe arm E. The

lever C also has notches, P P, lite., in which tbo'lcat'ohD is made tooperate and hold it in position when the axle has been raised.

The operatiouis very simple, and as follows: The loop F c'an be adjustedon either' of the notches' J by simply raising the arm E up parallelwith the lever C, the short end of which can then be pint under an axle,and the end,vB .,-brqught down as at lig. 1, and held iny place by 'thecatch D. i

Having .thus described my iuventionLI claim, and desire to secure byLetters Patent of the United States- A Wagon-jack having a lock arrangedwith a loop, F, arm E, and lug G, in combinz'rtiormvithl lever C,notched standard B, and catch D, substantially asand for the purpose setforth.

` ALEXANDER ROSS.
